The SpyderCHECKR software (beginning with version 1.2) is designed to work with either the 24 or 48 patch targets. The selection of the 24-patch chart or the 48-patch chart is called Mode. To choose the Mode, launch the SpyderCHECKR software and go to the Preferences. At the bottom of the window you will find the Mode selection to switch between SpyderCHECKR 24 and SpyderCHECKR 48 However, since most users will own one or the other target, the software’s default Mode is set according to the target originally activated. This means that those who own only one of the targets will never have to adjust the Mode setting. If you own both targets you will need to change the Mode to configure the software for the target you are currently using.
